Transition metal dichalcogenide based 2D/2D or 2D/3D van der Waals heterostructures exhibit superior properties for high-performance electronics, tunneling transistors, and catalysts. Here, we report on the fabrication of high quality MoS2/MoO2 with an atomic clean interface by one-step chemical vapor deposition. Optical microscopy, force Raman spectroscopy, scanning electron energy dispersive spectroscopy measurements reveal high-quality as-grown samples specific epitaxial relationship...
Twisted isotropic-anisotropic van der Waals heterostructures provide a platform for controlling the electronic and phononic properties of 2D materials inducing in-plane anisotropy in some isotropic materials. Herein, angle-resolved polarized Raman spectroscopy photoluminescence are used to investigate induced quasiparticles twisted MoS2/CrOCl heterostructures. Both phonons (Eg2 MoS2 Ag1 modes) excitons (A B excitons) represent strong orientation dependence, maximum intensities along...
Layered Palladium ditelluride (PdTe 2 ) is an interesting noble‐transition‐metal dichalcogenide with high electrical and thermal conductivity, exhibiting superconductivity a type‐II Dirac semimetallic phase due to the increased electron–phonon (e–ph) coupling. Herein, e–ph coupling constant λ of E g (in‐plane) A 1g (out‐of‐plane) modes in exfoliated PdTe nanoflakes via temperature‐dependent Raman spectroscopy within temperature range from 80 580 K determined. Both mode Gaussian line shape...
Interfacial interactions, including interfacial charge transfer and strain, play important roles in the applications of 2D layered materials. Recently, MoO 2 have been widely used as precursors or substrates for growth high‐quality MoS . Herein, photoluminescence (PL) Raman spectroscopy are to investigate dependence epitaxial monolayer PL properties on nanoflakes different thicknesses c‐sapphire. On all nanoflakes, trion exciton disappears due from The neutral exhibits a ≈60 meV redshift...
Van der Waals (vdW) epitaxial growth provides an efficient strategy to prepare heterostructures with atomically and electronically sharp interfaces. Herein, PbI2 was in situ thermally deposited onto exfoliated thin−layered CrOCl nanoflakes high vacuum fabricate vdW PbI2/CrOCl heterostructures. Optical microscopy, atomic force X−ray diffraction, temperature−dependent Raman spectroscopy were used investigate the structural properties phonon behaviors of The morphology films on substrate...
